I can't understand why gmdate() and date() reutrn the same values if my server is not configured to be on Greenwich Mean Time.
Why is this?
echo time(); // 1311011114
echo date("U"); // 1311011114
echo gmdate("U"); // 1311011114
echo date("j-m-y H:m:s"); // 18-07-11 12:07:14
echo date("e"); // America/Chicago
echo date("O"); // -0500
echo date("T"); // CDT
UPDATE
how do I obtain current time on Greenwich? calculating with date("O")? is there other way?
